Information technologies have become necessary in the area of the health sector, with the new trends that are emerging, this work aims to develop a prototype of a smart cane to improve travel, allowing to avoid obstacles that obstruct the path of visually impaired people. The methodology used was traditional through the stages of analysis, planning, design, development, testing and implementation, for the development of this prototype the Arduino IDE software was used, using as controller an ARDUINO ONE, for the control of distances, it was used HC-04 ultrasonic sensors, transmitting signals through the vibrating motor and a buzzer that emits a different sound depending on the programming of the ultrasonic sensors. All these connections were linked to an experimental table called Protoboard, which are directed to the ARDUINO ONE board. The final product allowed to have a cane that was tested with, people with visual weakness, the functionality was measured with a questionnaire that evaluated the mobility function and the results were greater than 80% of acceptance

In the study of different qualitative researches, evaluation questionnaires are used, these questionnaires have to be validated in their reliability, the present work presents the development of an information system that evaluates the reliability coefficient; using the Cronbach Coefficient formula, which allows estimating the reliability of a measurement instrument through a set of items, with Likert values from 1 to 5, where reliability is better the closer the value of alpha 1.0 is. . The methodology used for the development of the system is Scrum, it is an agile methodology where partial and regular deliveries of the final product are made, prioritized by the benefit that they contribute to the recipient of the project. Therefore, Scrum is especially suitable for projects in complex environments, where you need to get results soon, where requirements are changing or poorly defined, where innovation, competitiveness, flexibility and productivity are fundamental. The development of this evaluation system allowed evaluating 7 questionnaires applied to students of UTSJR, in the use of virtual platforms for software engineering subjects, it is worth mentioning that questionnaires or surveys can be evaluated to evaluate reliability in qualitative research projects.
